Extended Product Information

FAQs

What is the primary advantage of this long series flat bit?

The primary advantage is its extended length, allowing for deeper holes and access to awkward spots, combined with a design that promotes faster drilling and longer bit life.

What materials can this bit be used on?

This bit is specifically designed for drilling into various types of wood, both softwoods and hardwoods.

How does the 'positive cutting angle' benefit the user?

The positive cutting angle enables the bit to cut more aggressively, resulting in holes being drilled up to twice as fast as conventional flat bits.

What makes this bit last longer than standard bits?

It is made from high-carbon steel, heat-treated all over, with a hardened blade forged directly from the shaft, contributing to its durability and extended lifespan.

Will this bit work with any drill?

Yes, it is compatible with all standard drill chucks and can be used with both corded and cordless drills.

How should I clean the bit after use?

After use, clean the bit with a brush or cloth to remove wood dust and debris. A light application of oil can help prevent rust if stored for extended periods.

Troubleshooting

Bit not cutting effectively

Ensure the drill is set to the correct rotation (clockwise for drilling). Check if the cutting edges are clean and sharp. The material being drilled might be too hard for the bit.

Excessive vibration during use

Verify that the bit is securely tightened in the drill chuck and that the chuck itself is properly seated on the drill spindle. Ensure the bit is not bent.

Poor swarf clearance

Periodically retract the bit during drilling to clear accumulated wood chips. Ensure the drill speed is appropriate for the material and hole depth.
